ings, and more particularly to the full type thereof, wherein the raceway is completely or almost filled with the rolling elements. In bearings of this 4"type various means have been devised for introducing the rolling elements into proper position between the casing Lmembers, and a4 variety of expediente have been employed for this ur ose such as constructing the casinC91 7 b b members in sections, forming filling openings therein, varying the form of the tracks or ways, and other similar means. It is the purpose of my invention, however, to secure' the desired result, namely filling the raceway entirely or 'approximately with the rolling elements, Without resort to such eX- pedients and arrangements.

To this end I construct-the bearing por- ,tion of one .or both ofthe casing members vas a continuous ring, but of such reduced cross-section as to permit its deformation to a sufficient extent to allow the insertion of the rolling elements into the raceway, after `which its natural elasticity causes it to asn sume its proper and original form. I am aware that a discontinuous or split ring has been employed for the same purpose, but to avoid the "disadvantages therefrom arising, for instance, the interruption in the race-way due toits disconnected ends, I employ a continuous or unbroken ring and rely upon its reduced cross-section to permit of its deformation for the purposes specified.

In other words, I so reduce the ring that it will be of such thinness and flexibility as to require external support to give it the necessary rigidity for use in practice. When so reduced, the bearing ring may be supported or strengthened in any suitable manner, but I prefer to employfor this purpose a reinforcing ring which forms part of the bearing itself.' In the accompanying drawing I have disclosed in preferredform a bearing embodying my invention and provided with such; a continuous bearing ring of reduced Specification of Letters Patent.

I do not, liowe` desire to con-- fine myself to the for down and described, and generally spealri L, l? wish it to b e understood that the invention itself i s not limited to any specific foi-in or arrangement of parts except `in so far as such liiuitatimis are specified in the claim.

ring b1, for instance, may be connected to the bearing ring b by casting after the bearing is otherwise assembled, or in any desired or well known way. For instance, in my application for U. S. Letters Patent No. 408,010, led as of even date herewith, I have set forth such reinforcing means as comprising a plurality of parts which lare detachably connected to each other and to the bearing ring. In the drawing herein, I have shown the reduced bearing ring as constituting a portion of the outer casing member, but obviously it might be employed in connection with the inner' casing member, or with both casing members. Other variations will similarly suggest themselves to those skilled in the art, and I do not limit myself to the exact embodiment of the in-A vention shown, Which I have illustrated only in a preferred form, as many equivalents are equally comprised Within its scope.

Having thus described my invention, .its construction and mode of operation, what I claim and desire tolsecure by Letters Patent of the United States is as. follows:

In an antifriction bearing, the combination of inner and outer casing members and intermediate balls, one of said casing members comprising a continuous ring of reduced Across section and of freely deformable elastic material, said ring having on its face a relatively deep ball groove, forming a ball track continuous and uninterrupted throughout the ring, and capable of resisting heavy axial thrusts in both directions, and a stiff reinforcing ring of relatively greater cross sectional area, firmly applied to .the deformable ring and serving to maintain the circular shape of the latter.

In testimony whereof, I affix my signature in presence of two'witnesse's.
